Add HTS sequence This sequence adds a new tab stop in the current horizontal position. This means that tputtab must be look for the next tab stop in the tabs array instead of using a hard coded value offset. Also, CHT sequence XXX message is removed because it is not a vt10x sequence (as far as I know it is a vt50x sequence), and it is not implemented by linux virtual terminal neither by xterm.
